Pictograms representing six types of experimental conditions: replay of a running (R) profile used for passive translation in the dark (T), replay of a running profile used for visual flow (VF) presentation, replay of a running profile used for visual flow and coherent passive translation (VF + T), replay of a running profile used for passive translation during the presentation of a static image of the virtual corridor (TVS), running while experiencing coupled visual flow and translation (R + VF + T), and static running with congruent visual flow (R + VF).
